M42 for 2019 narrowband
This year in narrowband. Two attempts at colour mapping.
Need to get rid of the MPCC with this telescope as the image is better without. Too much star trailing with.

M31 first test of old 10 inch Newt
First test of the old 10 inch Newtonian I picked up. Focuser and dovetail were a mess, but with some work it could be good. Optically pretty sound though.

M40 (Winnecke 4)
Messier 40, also known as Winnecke 4. Basically it’s a double star, and an optical double at that!
It was discovered by Messier while he was looking for a nebula reported in the area by Johannes Hevelius. He couldn’t find it so he catalogued this double star instead. Most have been a slow night or something…
And why did I bother imaging it? Well it was in the only patch of clear sky there was and I only had a few minutes before it clouded over. Still, it’s another Messier object to add to my list 🙂
